Haven't seen anything about this posted (besides a
brief mention from madcow) anywhere so I thought I'd have a crack at it. After the Big Foot (square taper) and Fast Foot (hexagon taper) cranksets which, honestly, are somewhat hideously outdated, Tune has finally struck back
(silently) with the Smart Foot cranks. Its main feature is a 30mm axle and the ability to be adapted to MTB or Road, BSA, ITA, BB30 or PressFit30 shells as well as feature a whole range of spiders including MTB triple, double, road standard, compact as well as an SRM. Weight should be around 540-580g without chainrings and from what i've seen, the estimated price will be around €600. Watch out for these at Eurobike as they might pop up every now and then on different bikes all over the show. I found no mention anywhere on Q-factor or available lengths...
Personally, I find them quite pretty (yes, I dig the ano colours) but performance-wise I know they won't do it for me. I doubt they're even remotely as stiff as the much cheaper Rotor 3D (which I didn't find impressive either) and they're in about the same ballpark weight-wise so I say don't bother wasting money one a set unless you insist on crank arms with a "tune" badge...

And lastly, a production sample:
